The S2IP consortium, comprising SYSTRA and three other European engineering firms, has won a major contract with TELT (Tunnel Euralpin Lyon-Turin), the Franco-Italian company delivering the new rail tunnel link between Lyon and Turin. TELT is one of the largest rail projects in Europe.

The S2IP consortium has won Lot 2 for the civil engineering project management of the access tunnels between Saint-Martin-La-Porte and La Praz in the French Alps. The French section of the works represents 80% of the entire tunnel. The S2IP consortium will be responsible for project managing two single-track parallel tunnels, which are 22.1km in length.

The consortium comprises Setec, SYSTRA, Italferr and Pini Swiss Engineers. SYSTRA’s Italian subsidiary SYSTRA SOTECNI will also be involved in the delivery.

A project to meet the transport needs of the Alpine region

When it opens in 2030, the 57.5km-long Lyon-Turin tunnel will link the international stations of Saint-Jean-de-Maurienne and Suse. It will greatly improve the connection between France and Italy, as well as across Europe. It will reduce the journey time between Lyon and Turin from nearly 4 hours (3 hours and 43 minutes) to under 2 hours (1 hour and 47 minutes). Around 4.5 million passengers per year will use this route, which will bring substantial environmental benefits because more than a million of them will use this rail link rather than road or air.

SYSTRA active on TELT since 2002

SYSTRA’s involvement in TELT dates back to 2002. Over the years SYSTRA and SYSTRA SOTECNI have delivered a number of studies and preparatory assignments, including project management of the Maddalena exploratory tunnel.

SYSTRA holds three additional major contracts associated with the scheme: project management assistance for traffic and socio-economic studies; land acquisition in France managed by SYSTRA’s property development subsidiary SYSTRA Foncier; and reviewing pre-project and final studies.
